Abstract

The purpose of his study is for middle-aged women to classify workout level into 3 groups(50% level, 60% level, 70% level during 12 weeks and to figure out the appropriate workout level by ascertaining the effect of body composition, muscle damaged index and aging hormone.

Methods: The subjects for this study are middle-aged women having over 30% body fat, and assigned into 3 groups on the basis of workout intensity(10persons of 50% intensity, 10persons of 60% intensity, 70persons of 50% intensity). it was analyzed for data processing by doing two way anova of repetition method and established the level of significance around p< .05 on SPSS 18.0 Program after study.

Results: CK(muscle damaged index)was increased significantly from 70% group and among the groups, 70% group was extremely increased than 50, 60% group.

LDH was increased significantly from 60% and 70% group and among the groups, 70% group was extremely increased than 50% group. second, melatonin(aging related hormone) was increased significantly from 70% there's no difference among the groups.

DHEA-S was increased significantly from 70% group, among the groups, 70% group was extremely increased than 60% and 70% group.

GH was increased significantly from 70% group, among the groups, 70% group was extremely increased than 60% and 70% group. third, weight(body composition) was decreased for all, and there's none of dramatical difference.

Body Fat was decreased significantly from 50% group, among the groups, 50% group was extremely increased than 60% and 70% group. amount of muscle was increased significantly from 70% group, among the groups, there's no difference among the groups.

Conclusion: muscle damaged index was effectively changed in low exercise intensity, but, aging related hormone was effectively changed in high exercise intensity, especially, DHEA-S and GH was significantly increased than 50%, 60%. Body Composition wasn't changed in weight but, low exercise intensity is appropriate way in order to lose body fat and to make the result into being generalized, more various exercise intensity should be required.

Key words: muscle damaged index, aging hormone, body composition, obese-middle aged women.
